Zeek Braverman

Ezekiel "Zeek" Braverman (Craig T. Nelson) is the patriarch of the Braverman family, Camille's husband and the father of Adam, Sarah, Crosby, and Julia. He has dabbled in various careers, including being a soldier in Vietnam having graduated from West Point in the class of 1962, an activist hippie, an aspiring actor, and a shrewd entrepreneur, but none lasted more than a few years. He is 67 at the start of the series(as he is said to be turning 72 in season 6), making him four years older than his wife, Camille. In the first season it is revealed that he made a bad investment, causing his wife, Camille, and him financial hardship. Later, it is also revealed that he had an affair.[1] He doesn't get along with his mother, Blanche, who turns 86 in season three, which means that she was about seventeen when Zeek was born, as he would've been 69 in season three.
